Bum's don't even sleep in the open, yes there "roof" may be cardboard but point is, EVERYONE needs and wants a roof over there head. 

if I paid a poor tenant for their poor behavior, it would cause me to lose sleep.  

I do have sufficient cash of our own in our bank accounts to show we could cover the mortgage for ~6 months if it was unrented.  

So we wouldn't be losing any space by adding this extra 1/2 btr, on the contrary, it's pretty much a "dead space" and the tenants sleeping upstairs wouldn't need to go downstairs in the middle of the night or every morning - definitely more convenient

Hey @Philip Caslan, it looks OK but I will say that the house looks kinda empty here and there. 6 place seating for a house that sleeps 12?

It makes sleeping at night no problem. 

She was "horrified and couldn't sleep."

Is it sufficiently sized to cool the space?

For multifamily investments, using the LLC name is typically sufficient for legal and banking purposes, as advised by your CPA and banker.A DBA may be useful if you want a separate brand or manage multiple properties under different names, but it’s not required for most investors.

@Hansel Barretono, you buy the 4 plex with a low money down loan, and live in 1 unitisn't supposed to cash flow, just offsets your mortgage with the rentsbut of course you can even rent out the rooms in your unit and sleep in the basement or on a couch or whatever
